A-Level Chemistry Question Analysis Topic: Chemistry - Short Questions
Exam Questions:
1) Define the following terms:
(i) Glycosidic linkage
(ii) Invert sugar
(iii) Oligo saccharides
2) Which of the two components of starch is water soluble?
Answers:
For A-Level Chemistry, you should know:
1) (i) A covalent bond known as a glycosidic bond or glycosidic linkage joins a molecule of carbohydrates to another group, which may or may not be another carbohydrate.
(ii) A product of the hydrolysis of sucrose that contains a mixture of an equal amount of glucose and fructose. It is created artificially for use in the food industry and is naturally found in fruits and honey.
(iii) An oligo saccharide is a saccharide polymer that contains a few (usually three to ten) simple sugars (monosaccharides). Numerous processes, such as cell binding and recognition, involve the usage of oligosaccharides. Glycolipids, for instance, play a significant part in the immune response.
2) The two parts of starch are amylose and amylopectin. While amylopectin is not water soluble, amylose is.
